In the use of the hose-connecter herein s v2O, whichlatter Vis free. forrelative rotary and limited longitudinal movement with respectgto thehose-nipple 11,]is screwed upon the threadedv outer end 18 of thetire-valve i .nipple 171preferably ai distance suiicient to cause theupper end oi' the said nipple to engage the underface of thesealing-washer 23.

A 'ce -With our connecter thus in place, as shown in-Fig. 4, theoperating-lever 101s swung VVdownward-'from the position shown inthevsaid figure tothe posit-irony shown in Fig. 5,

with'the effect of' causingV its operating-lugs 31 and to depress thehose-nipple l1.

The described downward :movement of the hose-nipplell serves to vengagethe outer end of the valve-openingfplunger 10 with the-end ofv the stem12 yof the plunger valve-head 13, causing the latterrtomove away. fromthe l;seat-'member llagain-st thelcounterurge of the spring 15, solas topermit the ready entry of into `the tire;

The parts will,

, When itis desired to uncouple the con-` necter` from rtheVvalve-nippleV 25, the operating-lever l() is 'swungupward'from-the,position shown in Fig. k5 to the positionshown inV Fig. fl to permitthe spring l5 to re-seat the valve-headl. The entire connecter may nowbe removed from the nipple 17 by reversely rotating the body-memberY 20without having permitted any-appreciable amount of -air toescapefromfthe tirefor similar article which has ust been'inated.

Furthermore, while we have shown and described herein an improvedconnecter designedto be applied to the end of a hose, it is obviousthat. it may be rigidly attached to a portable pump-structure, ifdesired, without impairing its usefulness.`

1. A hose-connecter comp-rising a bodymember-adapted to be sleeved over'and connected to a valve-nipple; a hose-nipple mounted in the saidbody-member with capacity for movement therein; a valve-opening plungercarried by the outer end of the said hose-nipple in position to engageareciprocating valve-stem to depress the same; and an operating-'memberavailable for manipulation from the outside of the hose-connecterstructure and operatively connected .to the said hose-'nipple foreffecting the movement of the said plunger; whereby a valve may beJforced open after the connecter lhas been applied to valve-nipple orthe like to permit the ready passage of air therethrough withoutappreciable leakage duri-ng the valveopening'operation.

2. A hose-connecter comprising a hollow body-member ormedwith aninternal shoulder and adapted to be sleeved over and connected to avalve-nipple; a hose-nipple mounted in the said body-member with cat.member available for manipulation from the outside o f thehose-connecter structurey and operatively connected to the saidhose-nipple for effectingY the movement of the said plunger against thecounterurge of the said resilient ring.

In testimony whereof, we have lsignedy this specification. v YFREDERICK-E. HALL.
